The reality star decided to go public to encourage other men to get checked, after having his own health scare when he was a teenager and three operations on his left testicle.

He revealed on This Morning that his cousin had testicular cancer and that both of his brothers were infertile.

He also admitted that he didn't get examined until he was 20 years old, saying: "Because it doesn't come with a lot of pain it's easy to neglect.

"Everyone thinks they know their body. There's a right way to check them. I'll be honest with you it's not something you grab hold of in everyday life. You wash yourself but don't necessarily use your fingers to identify."

Testicular cancer is the most commonly diagnosed cancer in young men, and Cancer Research UK says around 2,200 men in the UK are diagnosed each year. It is more likely if you have a family history of the disease.

But research from male cancer charity Orchid shows that 68% of men don't know how to check their testicles properly.

The Movember Foundation's advice is: "If you notice a change in size or shape, a lump that wasn't there before, or if they become painful to touch, see a doctor."

Chris echoes their message: "Testicular cancer is a silent killer, men need to realise this and check themselves regularly. It takes 10 seconds. Please do it."
